MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 374,394, dated December 6, 1887.

Applicatit n filed May 5, 1887. Serial No. 237,184.

To calla/17mm, it may concern:

Be it known that I, LoUIs OAMPIoHE, of Ste. Oroix, Switzerland, have invented certain new and useful Improvements in Music-Boxes, of

which the following is a full, clear, and exact description. I

The object of my invention is to provideimproved means for moving the pin-barrel in its longitudinal direction, and also to simplify the speed-regulating gear.

The invention consists in pivoting to the frame of the mechanism adjacent to one end of .the pin-barrel a plate having its pivot at unequal distances from its faces and points on 1 its corners, which points are acted upon by a recess in the end of the pin-barrel to turn said plate, which turning of the plate causes the I pin-barrel to move along its shaft to change the tune.

The invention also consists of a novel speedregulating gear, dispensing with a majority of the wheels and pinions for driving same now used in the ordinary musicbox, and in details of construct-ion and combination of parts, as will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this specification, in which- Figure l is a plan view of a musicbox embodying my improvements. Fig. 2 is a sectional view on line 00, Fig. 1. Fig.3isaview showing myimproved pin-barrel-moving device in the act of shifting the barrel, part of the frame-work being broken away. Figs. 4 and 5 are similar views to Fig. 3, showing the barrel-moving device in the respective positions it assumes after having shifted the barrel. Figs. 6, 7, and 8 are views of separate barrelmoving plates arranged to produce different numbers of tunes.

A in the accompanying drawings represents the frame; B, the pin. barrel; D, the comb, and E the mainspring barrel and casing, which are of the ordinary or suitable construction.

a is a plate swiveled or pivoted in the frame A, preferably in a recess formed in the said frame. The plate a is made with sides that are at varying distances from its pivot and 50 has projecting points at the corners, as shown.

(No model.)

The pivot of the plate a is a little to one side of or out of line with the axis of the pin-barrel shaft 1).

dis a recess formed in the end of the barrel B, and so arranged as to engage one of the points on the plate a as said pin-barrel revolves. The pin-barrel B is pressed into engagement with the plate a by means of the spring e, Fig. 1. This barrel-shifting device operates as follows: When the barrel operates to produce 'music,two of the points of the plate a will bear against the barrel, asin Fig. 5; but as soon as the recess (1 arrives beneath one of these points the pressure exerted by the spring 6 will be applied only to the other of these two points, and the cylinder will be pushed as it turns, so as to engage the one point in the recess d, thereby turning the plate a into the position shown in Fig. 3, and from that into the position shown in Fig. 4. In the same manner the plate a will be turned back from the position shown in Fig. 4to that shown in Fig. 5, the point a first entering the recess d. The plate a having one face farther from the pivot than the next, it follows that when one face of said plate is presented to the barrel, as seen in Fig. 4, said barrel will be pressed nearer to the pivot of said plate, and when the other face of said plate is presented to the barrel, as seen in Fig. 5, the barrel B will be held farther away from said pivot, and thus by turning the plate a the tune will be changed. The plates a shown in Figs. 3, 4, and 5 are arranged to move the barrel to produce two tunes only, while those shown in Figs. 6, 7, and 8 may be used in music-boxes to produce three, four, and six tunes, respectively. The. plates to may be provided with any number of faces and points to move the barrel to produce any desired number of tunes.

Heretofore tune-changes depending upon a projection and recess on barrel B have been used. By my invention I do away with every projection on said barrel. The shaft 1) carries a pinion,f, which is driven by a crown- 5 wheel on the mainspring-barrel E. The shaft 1) also carries a spur-wheel, F, which gears with a vertical worm, g. The worm gis journaled in the two horizontal armsh of abracket,

H, which bracket is secured to the frame A. 10c

The outer ends of the arms 7b are braced by the screw-rod Near the upper end of the worm g is secured the pinion j, which meshes with the horizontal worm Is, one end of which is 5 journaled in the vertical part of the bracket H, the opposite end of said worm is being journaled in a lug, m, projecting downward from the upper horizontal arm h. The worm 70 carries the fan J, which passes through an 1 opening, a, in the upper horizontal arm 71, as

best seen in Fig. 1.

L is a cap secured to the upper arm h of bracket H, and placed over the bearings of the worms 9 and 7c, and held there by means of the screw 0. (See Figs. 1 and 2.) The barrel B is stopped at the right position by means of the lever M, which is pivoted to the frame A, the longer or inner arm, 8, of which is pressed into an aperture in the toothed wheel F by 0 means of the spring q whenever said'hole comes opposite the end of arm 3. An arm, 1-, of the lever M projects upward, so that as the arm 8 drops into the aperture of wheel F said arm 1 will engage the Ian J and prevent its 5 revolution. As the lever M is withdrawn to release the pin-barrel B, the arm 7 will be simultaneously moved out of engagement with the fan J. lVith this construction the fan is brought nearer the source of power, thereby having projecting points at the corners and adapted to hold two of said projecting points normally'in contact with the springpressed pin-barrel B, in combination with said pinbarrel having the recess d, but no projection near said recess, substantially as described.

2. The pinbarrel 13, having recess d, but no projection near said recess, in combination with the swiveledplate a, having projecting points at the corners and having its faces at varying distances from its pivot, said plate being arranged to normally hold two of its projecting points in contact with said pin-barrel while the tune is being played, substantially as described.

3. The pin-barrel B, having recess (1, but no projection near said recess, combined with spring 6, and pivoted platea, havingprojecting points at its corners, the pivot of plate a be ing on one side of the axis of the pin-barrel, substantially as described.

4. The spring-barrel E and gearing joining it to the shaft Z), in combination with the shaft I), toothed wheel F, vertical worm g, horizontal worm is, and bracket H, substantially as described.

5. The bracket H, having the horizontal arms 71, and vertical lug in, in combination with the horizontal worm 7c and vertical worm g, substantially as described.

6. The angular cap L, made in one piece, combined with the bracket H, and adapted to cover the ends of the horizontal worm 7c and vertical'worm g, substantially as herein shown and described.
